Limit error retries

Post by keithhelms »

Is there any setting to limit the number/time makemkv will retry when getting a drive error? I've run into a couple of those scsi errors recently and it seems like makemkv just keeps trying over and over again. That can't be good for the drive.

Look at the IO tab in Preferences.

Preferences->IO, Read Retry Count.

Note that this only applies to the number of times MakeMKV will request a retry, after the operating system reports an error; the operating system may make retry requests before MakeMKV is notified of an error.

It looks to be set to 5 by default. Is that "per bad sector"? If there's a problem where the computer and drive are not talking correctly, wouldn't that mean makemkv just moves from sector to sector and retries all of them 5 times? Every once in a while I get errors like this:

MSG:2003,0,3,"Error 'Scsi error - HARDWARE ERROR:TIMEOUT ON LOGICAL UNIT' occurred while reading '/BDMV/STREAM/00040.m2ts' at offset '1241088'","Error '%1' occurred while reading '%2' at offset '%3'","Scsi error - HARDWARE ERROR:TIMEOUT ON LOGICAL UNIT","/BDMV/STREAM/00040.m2ts","1241088"

Where the drive just won't work again until I power cycle the system. Then it picks up and starts working again. Before I notice the problem and kill makemkvcon, it justs spits out errors endlessly. The drive is less than a year old, so it shouldn't be going bad yet and it works for many discs between these "spells".

If a 5th retry gets a good sector read, but the next sector comes up bad for 4 tries, continuously, yes, it would retry every sector.

However, if it fails 5 retries, the read of that file will be aborted.
